Aluminium Frames

Replacement sealed units for aluminium window and door frames. Aluminium frames demand precise measurement and slim-profile units — rebate depths are typically tighter than uPVC, and tolerances are less forgiving. We manufacture sealed units from 14mm upward, including slim double glazed and heritage profiles, with exact-size precision for clean aluminium reglazing.

Aluminium frames from Schuco, Smart Systems, Reynaers, Kawneer, Aluk, or heritage systems — we manufacture units to fit every profile.

Expert Glazing, Done Right

We're not a national call centre. We're local glaziers who take pride in every job.

Slim-Profile Units

Aluminium frames often have shallow rebates — especially heritage and 1980s-90s systems. We manufacture slim units from 14mm overall thickness. Tight tolerances ensure clean engagement with narrow aluminium beads.

Thermal Break Awareness

Modern thermally broken aluminium performs well. Older non-thermally-broken frames are cold — upgrading the glass to Low-E + argon helps, but set realistic expectations about frame-area cold bridging.

Heritage & Conservation

Period properties with original aluminium frames often require like-for-like visual appearance. We match original glass configurations while discreetly upgrading the specification where possible.

5-7 Day Standard Turnaround

Aluminium units are typically bespoke sizes. Standard turnaround is 5-7 working days. Rush orders available for urgent commercial or conservation projects.

10-Year Warranty

Every unit carries our 10-year warranty — including slim-profile and heritage configurations.

Aluminium is less forgiving than uPVC. Measure carefully, note the system type, and check these details before ordering.

Aluminium Reglazing: Specification Guide

Aluminium Frame Types

Aluminium windows fall into three broad categories, each with different reglazing characteristics:

Heritage / Conservation — Slim profiles designed to replicate steel windows in period properties. Rebate depths typically 14-18mm. Require our slimmest sealed units. Often in Listed Buildings or Conservation Areas where visual appearance is controlled.

1980s-90s Domestic — The first generation of aluminium replacement windows. Non-thermally-broken profiles with 20-24mm rebates. Common in extensions, porches, and conservatories of this era. The frames are often in good condition but the glass is basic clear — prime candidates for specification upgrade.

Modern Thermally Broken — Current-generation aluminium systems (Schuco, Smart, Reynaers, etc.) with thermal breaks and deep rebates (28-44mm). Accept the same unit thicknesses as uPVC. Reglazing is straightforward with precision measurement.

Slim-Profile Units

For heritage and older aluminium frames, we manufacture sealed units from 14mm overall thickness:

14mm (4-6-4) — The slimmest double glazed unit. For heritage frames with minimal rebate depth.
16mm (4-8-4) — Slightly better thermal performance. Fits most heritage systems.
20mm (4-12-4) — Good thermal performance in a slim package. The sweet spot for 1980s-90s aluminium frames.

All slim-profile units can include Low-E coating — even at 14mm. The coating adds zero thickness and significantly improves thermal performance.

Thermal Break Considerations

Non-thermally-broken aluminium frames conduct heat rapidly. Even with excellent glass, the frame itself will feel cold and may cause perimeter condensation. Be honest with customers about this limitation. New glass will improve the glazed area dramatically, but the aluminium frame sections will remain thermally weak. For comprehensive thermal improvement, frame replacement may eventually be needed.

Aluminium reglazing has the highest callback rate of any frame type — almost always due to measurement error. Measure width at top, middle, and bottom. Measure height at left, centre, and right. Use the smallest dimension in each axis. Deduct 4mm total. Double-check before ordering. A remake costs you time, money, and credibility.

Precision measurement, clear specification, reliable delivery. The aluminium reglazing workflow.

How Our Service Works

From first contact to finished job, we make the whole process straightforward and stress-free.

Survey the Frame

Identify the system type and glazing method. Measure rebate depth, width, and height at multiple points. Note gasket type and drainage. Take photos of the frame profile and bead system.

Specify the Unit

Tell us the frame system (if known), rebate depth, and desired specification. We'll recommend the optimal unit thickness, pane configuration, and glazing medium.

Order with Confidence

We confirm every aluminium order specification before manufacture. Trade accounts get 30-day terms. Volume discounts for multi-unit projects.

Precision Fit

Units dispatched within 5-7 working days. You fit — allow extra time for aluminium (gasket placement, pressure plate alignment). The precision pays off in a clean finish.
From 14mm slim heritage units to 36mm modern specifications — every configuration for aluminium reglazing.

What We Can Help With

From quick repairs to complete replacements, we handle all residential and commercial glazing needs.

Slim-Profile (14-20mm)

Heritage and older aluminium frames. 14mm, 16mm, and 20mm units with optional Low-E coating. Precision manufactured for tight aluminium rebates.

Low-E Upgrade (24-28mm)

Modern thermally broken aluminium frames. Low-E + argon units delivering 1.1 W/m²K in standard aluminium rebate depths.

Triple Glazed (32-36mm)

Deep-rebate modern aluminium systems. Triple glazed units for maximum thermal performance. Check rebate depth before specifying.

Acoustic for Aluminium

Acoustic laminated units in slim and standard profiles. Ideal for aluminium-framed properties near roads or railways.

Heritage Appearance

Units that replicate the visual appearance of original glazing — slim profiles, period-appropriate configurations. Conservation officer friendly.

Safety & Security

Toughened and laminated options for doors, low-level panels, and overhead glazing in aluminium frames. All thicknesses available.

    Huge shout-out to Ollie and the team! ⭐⭐⭐⭐⭐ ​Our patio door went from being completely stuck and impossible to lock to sliding like a dream. Ollie diagnosed the issue (collapsed wheels) and his team squeezed us in despite a packed schedule. ​The difference is night and day—it literally feels like it’s sliding on air now.

    We had glass panes and hinges replaced throughout the house and a new set of french doors. Ollie and everyone that came to fit were friendly, professional, tidy and considerate. The work has been carried out to excellent quality - especially the french doors which look fantastic.

  • ★★★★
    Complex issue with a broken non-standard hinge on 1st floor window. Ollie was the only one of over 10 other firms I contacted who said they could do the job. It took a while, but Ollie managed to source a replacement part and completed the job to a high standard. Very happy with the work done and have asked him to do another job following the good experience.

Common questions about replacing sealed units in aluminium frames.

Frequently Asked Questions

Everything you need to know about our double glazing repair and replacement services across the South West.

  • 14mm (4-6-4) — our slimmest double glazed unit, designed specifically for heritage and slim-profile aluminium frames. Low-E coating available at this thickness for improved thermal performance without adding bulk.

  • Yes — this is one of our most common aluminium jobs. 1980s-90s conservatories with basic clear glass benefit enormously from Low-E + argon upgrades. Most use 20mm or 24mm units. The conservatory becomes usable year-round instead of freezing in winter and roasting in summer.

  • Look at the frame cross-section from the side. Thermally broken frames have a visible polyamide strip (usually black) separating the inner and outer aluminium sections. Non-broken frames are solid aluminium all the way through — they'll feel cold to the touch in winter.

  • Match whatever the frame was designed for. Never substitute tape for gasket or vice versa — the glazing pressure and drainage characteristics are different. If unsure, check with the frame system supplier or send us a photo of the rebate profile.

  • 2mm per side (4mm total) for aluminium. This is tighter than uPVC (3mm per side) because aluminium doesn't flex. Measure precisely at multiple points and use the smallest dimension.

  • Yes. We manufacture units for Schuco, Kawneer, Reynaers, and other commercial curtain wall systems. Provide the system type and rebate dimensions — we'll confirm compatibility and quote accordingly.
